An intact organonitrogen bridge is formed when ethyl diazoacetate or phenyl azide add across a ZrIr bond (for example, 1 ; Cp = C 5 H 5 , Cp * = C 5 Me 5 ). The ethyl diazoacetate complex is thermally stable, but heating the phenyl azide complex 1 leads to first‐order loss of N 2 and formation of the bridging phenylimido complex.
